Why is it easy for real-world assets to fail on the chain? To put it simply, the problem isn't with the blockchain itself, but with the bunch of off-chain files, contracts, and certificates.

For example, a solution like a leading oracle can indeed handle price data, but they only deal with transmitting numbers. The real trouble is: transaction documents, asset certificates, ownership records—have these been tampered with? When were they changed? No one really knows.

IOTA has a concept in this area. Through a notarization mechanism, transaction documents, certificates, and asset records are directly inscribed onto the ledger. This way, you have a solid proof: at a certain point in time, the data looked like this, and whether it has been altered since then is clear at a glance.

Simply put, the circulation of RWA involves not just value, but also trust. And the foundation of trust is: this data has not been tampered with. IOTA's approach makes this verification process a default system behavior.
